IMPROVEMENT IN RAILWAY-RAIL CHAlRS.

Specification forming part of Letters Patent No. 142,359, datedSeptember 2, 1873; application filed v I July 23, 1872.

To all whom it may concern:

Be it known that I, Lnvr BARTLETT TYNG, of Lowell, in the county ofMiddlesex and State of Massachusetts, have invented a new and ImprovedCombined Railroad-Chair and Fish-Plate; and I do hereby declare that thefollowing is a full and exact description of the same, reference beinghad to the accompanying drawings and to the letters of reference markedthereon.

In the present state of the art of railroadbuilding it has becomeessential to have the rails continuously bearing, so as to give ease ofmotion to the carriages, and, in order to efiect this, to'employfish-plates to unite the rails, and dispense with chairs for thatpurpose. Moreover, to avoid vertical fiexure of the rails, which lessensthe speed of trains and makes greater power necessary in thetraction-engines, it has become essential to make the rail of greatervertical diameter, and

, consequently it becomes more diificult of support against lateralpressure, and fish-plates alone are not sufficient for that purpose.

The object of my invention is to provide a rail-joint which shall unitethe advantages of the chair and of the fish-plate, giving both verticaland lateral support, and which may be made at a cost which will permitits introduction into general use; and my invention consists in thepeculiar construction of my combined chair and fish-plate, in whichthick and rigid sides are combined with a thin and somewhat elastic seatand connections, made in one piece. 7

In the drawings, Figure 1 is a cross-section of a railwith my deviceshown in position in connection with the rail, in dotted lines, and inthe same figure my device is shown in black lines in the form in whichit issues from the rolls.

device.

Like letters denote similar parts in each figure.

Fig. 2 is a plan view from above of my A represents a railroad-rail ofwell-known form, and B the combined chair and fish-plate, which is madeout of suitable metal in one piece, by rolls and other machinery which Ihaveinvented, and which will be the subject of a separate applicationfor Letters Patent. In the construction of this chair and fish-plate thesame will be rolled out in the form shown in the black lines of Fig. 1,and at as great a length as possible, and afterward cut off into thelengths required for use, which in rails of ordinary size will be aboutfifteen inches. It will be observed that in this shape the parts marked(3, which are the fish-plates proper, are very much thicker than theother parts, and in actual use are made at least threefourths of an inchthick. The outer ends a of these parts are beveled at an angle to makethem fit closely under the shoulder b of the rail. The bottom G of thechair and fish-plate is made in use about three-eighths of an inchthick, and at either end of said bottom are the wings E, of the formshown in Fig. 1,.and quite thick, and between said wings and the plates0 the plate shown by the letter F is drawn quite thin, or aboutthree-eighths of an inch in thickness. After my device, as shown in Fig.1 in black lines, is rolled out and cut off, as before named, it ispunched, as at c, for the bolts, which will be commonly four in number,or two to each rail, and then bent in rolls-also, of myinvention, butnot yet pat entedwhich turns the wings up into the position shown in thedotted lines in Fig 1, one

of the black lines of the wings assuming a horizontal position andmaking a portion of the bottom of the chair; the other black lineassuming a vertical position and making the outer edge cl of said chair,the part F assuming a shape corresponding to and intended to fit closelyto the top of the foot of the rail,

and the fish-plate 0 taking a vertical position and intended to have itsupper'beveled end a fit closely to the shoulder of the rail, while itslower end fits also closely to the top of the foot of the rail. It willbe seen that in this vertical position of the fish-plate there is aspace, 6, be-

- tween the inner side of this plate and the web of the rail. Thisshape, however, as it comes from the machine, is not precisely like thatshown in the dotted lines, as the fish-plates are intended to be sprunga little into place when the nuts'to the bolts are set up, and the partsare then drawn closely to the corresponding portions of the rails. Aftermy device is thus shaped rectangular slots D are punched out of the'edged of the bottom of the chair.

in solid metal, not penetrating the interior rolls differ a little insize.

of the chair, and my device is ready for ap plication. In use the endsof two rails are slipped into it, or it is driven upon them and therails secured to the same by bolts H in the usual manner, and the chairsare spiked down to ties by spikes passing through the slots D.

Among the advantages of my device are the following, viz: The close fitof the parts to the rail and the fastening of the device to the tieprevent the rails from running or moving in the direction of their1ength,which is a serious difficulty in railroads having heavy grades,and is now remedied by notching the rails for the spikes, which methodhas been found objectionable, particularly in steel rails, which areliable to break at such points. The thinness of the bottom of the chairgives a spring to the same, which enables it to receive two railswithout cutting away any part of the rail or the chair, which is animportant matter in practice, as rails rolled in the same The thicknessof the fish-plate portion of my device, its vertioal position, and itsclose fit serve to hold the rail strongly in its vertical position,while it is assisted in preventing lateral flexure by the strength ofthe chair and by the chair being fastened to its tie. By the springingof the parts a little together to embrace the rail the nuts to the boltsare less liable to work loose, and the objectionable pounding of therails found in the use of the ordinary chair is provided against,because the rail is held firmly to my device without play, and yet mychair has a certain elasticity upon its tie. The ad vantage of slots inthe solid metal for spikes is obvious upon inspection.

Having thus described my invention and some of its advantages, I wishtodisclaim the invention, broadly, of a wroughtmetal combined chair andfish-plate made in one piece; but

What I do claim as my invention, and wish to secure by Letters Patent,is-- The combination, in a combined chair and fish-plates made ofwrought metal in one piece,

of thick rigid side pieces to serve as fish-plates,

and their elastic connections extending from the bottom of said sidepieces entirely around the foot of the rails to support and secure saidside pieces and to serve as a chair, being constructed withside-projecting base with spike-notches cut therein, as and for thepurpose described.
